Abstract:
Objective To evaluate the development of aortic arch in children with coarctation of aorta (CoA) using CT. Methods CT data of 47 children with histopathologically proved CoA (CoA group) and 47 children with non-cardiovascular diseases (control group) were retrospectively analyzed. The maximum internal diameter of ascending aorta (AOA), the proximal arch segment (D1), the distal arch segment (D2) and isthmus (D3), the maximum inner diameter of the descending aorta at the diaphragm (DA) were measured. The ratio of D1/AOA, D2/AOA, D3/AOA and DA/AOA were calculated. The differences of the above parameters were compared between the two groups, and the correlation between the above parameters and age were analyzed. Results The ratio of D1/AOA, D2/AOA and D3/AOA in CoA group were lower than those in control group (all P<0.01). There was no significant difference in DA/AOA between the two groups (P=0.3263). In CoA group, aortic arch dysplasia was found in 26 children, including 11 of D1/AOA≤0.6, 15 of D2/AOA≤0.5 and 13 of D3/AOA≤0.4. No obviously correlation was found between D1/AOA, D2/AOA, D3/AOA, DA/AOA and age in both two groups (all P>0.01). The ratio of D1/AOA, D2/AOA and D3/AOA greater than the congenital heart disease database classification standard in 5 children with active arch dysplasia who were followed up. Conclusion Children with CoA often have aortic arch dysplasia, and dysplasia in the posterior arch is common.
